On the 29th of June the government gazetted a proposed plan for artificial reefs to be built inside the Brothers Marine Park, to improve the habitat and boost fish numbers. The artificial reefs will cover around 0.7 hectares inside the 66-hectare marine park off Lantau to the east of the airport.

The works are tentatively scheduled to start at the end of 2018 and should be completed by 2019.

The marine park has been identified as an important habitat for endangered Chinese White Dolphins, and a spawning ground for commercially important fish species.
